yes, it does it with two passes, but it may
use very tricky color and blending modes...
the abundance of tricks you can do with
colorcombine and alphacombine on 3dfx is
not easily mapped onto redline/verite...
this is perhaps the weakest (and at the same
time most complicate) spot in the wrapper
currently....
the whole mapping process should perhaps
be thought about again and should be built up
from the ground in a future version of the
wrapper, but I am quite sure that you will
always stumble over combinations which you
can't handle well....
(there are some glide tricks which you can't
map at all, I am afraid...)
One of main sources for difficulties is
verite's limitation that there is always
just one SRC_FUNC for both the color and alpha
channel.... 3dfx let you configure the two
channels separately and VERY flexibly....
..oh my...
